It's a powerful trimmer, and they are only getting rid of it (that kit) because it contains the 8ah HO in it, as we should soon see on the mower

. Scan your receipt to your email, you will need it on the batteries down the road.
I have never found my Gen1 QuikLok capable trimmer incapable of what I need it to do, and you can find those for ~$140 new pulled from kits. So depending on your future needs, the attachment capability (and weight of 2 batteries) keep most from choosing this model.
